Set the same fixed height or js set the height after loading.

If it is adaptive, it has to be implemented in js

Yes, this method can solve it. How to use JS to solve the problem of equal heights
It is recommended that the poster should not learn how to use JS to achieve equal heights, because this goes against the principle that scripts do not control the basic layout; secondly, the above methods mainly use one positive margin and one Negative padding is a technical process, but this has side effects, and it smells a bit like timing*. Personally, I think that in fact, many web designs do not need equal heights. They can usually be done with background colors, or many background colors are originally blank. .
